I have an external disk which I reformatted as exFAT so that it would be readable by all platforms. Ever since I did that I have problems with it. I have been able to work around the problems up until now. I'm just trying to move the files off of it onto another disk and I've moved 90% of them but the final 10% might be lost. I can do the terminal commands:
mv /volumes/bad_disk/hey.txt /users/me/hey.txt
and although that command will succeed in moving the file, the disk sort of crashes after that. If I wait about 5 minutes, or I restart my computer, or unplug the disk and plug it back in, then it will be operable again. I'm using a MAC.
Another strange behavior is that sometimes when I use the above command
mv /volumes/bad_disk/hey.txt /users/me/hey.txt
The operation will take about 3 minutes and make a lot of the other operations on my mac inoperable but it will get the job done eventually.
Any tips would be appreciated.

1The drive's symptoms aren't really like anything I've seen, so I can't give much advice. But I will recommend one thing: use
cpinstead ofmv.mvbetween volumes essentially copies the file (likecp), and then tries to delete the original. Making unnecessary changes (like deleting files) on a failing volume can cause volume structure corruption, contribute to its physical failure, and is generally just another thing to go wrong. Actually, if possible I'd mount the volume as read-only to prevent anything like this. – Gordon Davisson – 2019-11-04T18:08:47.817
